摘要： A compacted and highly oriented microstructure of the bulk-shaped Bi-Sr-Ca-Cu-O system oxide superconductor is obtained by the intermediate pressing method of the present invention. The growth rate of the high critical temperature phase in the bulk of Pb-doped Bi-Sr-Ca-Cu-O system oxide superconductor is also much improved and the sintering duration for obtaining a single phase having a high critical temperature is shorteneed by this method. Additionally, a higher critcal current density of Bi-Sr-Ca-Cu-O system oxide superconductor is obtained by the working under pressure process after cooling between a first and a second sintering step. Furthermore, the magnetic field dependence of the critical current density of Bi-Sr-Ca-Cu-O system oxide superconductor is also improved by the method of the present invention. The thus intermediate pressing process between the first and second sintering step of the present invention may be applied so easily as to facilitate the manufacture of tapes, wires, discs or the like of the Bi-Sr-Ca-Cu-O system oxide superconductor.

摘要： A substrate electrode having a plurality of substrate holders capable of causing a substrate to tilt by an arbitrary angle .theta. relative to the horizontal plane is provided. A plurality of auxiliary electrodes are arranged substantially vertically below the substrate electrode and between the substrate electrode and a target. The substrate electrode and the auxiliary electrodes are electrically insulated from the target. Bias voltage applied to the substrate electrode and the auxiliary electrodes causes the plasma boundary between the cathode dark space and the negative glow to form a cathodic plasma space having a parabolic section, thus forming a crystal-oriented thin film on the substrate surface.

摘要： This invention provides a production method of Nb3Al superconducting multifilamentary wire based on rapid-heating, quenching and transformation method, capable of producing a high-performance Nb3Al superconducting multifilamentary wire by improving critical temperature thereof, upper critical field and critical current density. Upon a first stage heat treatment of beating a composite, in which bcc phase Nb—Al supersaturated solid solution is dispersed in Nb matrix, the bcc phase Nb—Al supersaturated solid solution ordered in temperature rise process is made disordered at an initial phase thereof and a non-reacting portion located adjacent is heated using a reaction heat generated when transforming this disordered bcc phase to A15 phase. Then, disordering of the bcc phase is promoted while propagating a high-temperature transformation region so as to automatically progress high-temperature beat treatment. As a result, a reaction-transformation is caused to block stacking fault from being generated in the A15 phase and crystal grain from being coarse and then, a second stage heat treatment for improving a long range ordering of the A15 phase is carried out.
